A film doesn't have to be morally right to enjoy or be entertained. It's just like watching a series where the protagonist is a robber or a criminal.

Yes, what the ML and FL have can be called cheating. The heart transplant can't be an excuse. But I still enjoyed it. The sceneries, the acting, the plot, the story flow, I love everything.

I searched if it is really possible to inherit the heart donor's memory. The answer I got from the internet is what this series also explained. I'm amazed.

So, I think the viewers should not rate a film base on their morals. The quality should be the basis here. It's actually boring to only watch about good people. I want to slap and curse the main characters too.

Well, it's just my opinion. But if you're not into this kind of complicated story, just don't give it a try.
